When an acid or a base is added to a buffer, a double-displacement reaction will occur. The acid or base will be neutralized, forming a neutral salt or water plus the conjugate of the buffer. For example, if the base NaOH is added to a buffer containing HCN and NaCN, the base will react with the acid HCN as shown: NaOH(aq)+HCN(aq)?NaCN(aq)+H2O(l) Complete the following chemical equations to show what happens when HBr or KOH is added to a buffer solution made from HF and KF. Part B Identify the reaction that occurs when the acid HBr is added to the buffer solution. Drag each label to the appropriate target.
HF (aq) + KBr (aq)
H2O (l) + KBr (aq)
HBr (aq) + KF (aq)
HF (aq) + KF (aq)
H2O (l) + KF (aq)
HF (aq) + HBr
BUFFER SOLUTION: HF (aq) and KF (aq)

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
